Embodiment
In the present invention; so-called amine and the tartaric salt of optically-active diacyl that uses as raw material, salt arbitrarily below can using: non-optically active amine and the tartaric salt of optically-active diacyl, racemic modification amine and the tartaric diastereoisomeric salt of optically-active diacyl, optically active amine and the tartaric salt of optically-active diacyl.In addition, salt arbitrarily below can using: with optically-active diacyl tartrate with racemic modification amine optical resolution, the diastereoisomeric salt of the optical antipode that contains in crystalloid diastereoisomeric salt that filtering separation obtains or the filtrated stock.At this, no matter the optical purity of the amine that contains in the salt is that what value can be used.In addition, the kind of amine is not particularly limited, can enumerates benzyl amine or cyclo-hexylamine etc. as non-optically active amine.In addition, racemic modification amine also is not particularly limited, can enumerates aliphatics amines such as 1,3-aminobutane, the amino valeronitrile of 3-, 2-cyclopropyl Trans-4-Amino Cyclohexanol; Alpha-Naphthyl ethylamine, α-phenyl ethyl amine, 1-methyl-3-phenyl propyl amine, α-(rubigan) ethylamine, α-aromatic amines such as (toluyl ethyl) amine; 3-amino-pyrrolidine, 3-amino-1-benzyl-pyrrole alkane, 3-phenyl-heterocyclic amines such as 1-propyl group piperidines.
Can enumerate benzoates such as optically-active dibenzoyl tartaric acid, optically-active two toluoyl base tartrate, optically-active two toluoyl base tartrate, optically-active two toluoyl base tartrate, optically-active two anisoyl tartrate, optically-active two meta-methoxy benzoyl tartrate, optically-active two O-methoxy benzoyl tartrate as optically-active diacyl tartrate; Phenylacetic acid esters such as optically-active phenylbenzene ethanoyl tartrate; Aliphatic carboxylic acid esters,'s classes such as optically-active diacetyl tartrate, optically-active dipropyl acyl group tartaric acid, preferred optically-active dibenzoyl tartaric acid, optically-active two toluoyl base tartrate, optically-active two toluoyl base tartrate, optically-active two toluoyl base tartrate, optically-active two anisoyl tartrate, optically-active two meta-methoxy benzoyl tartrate, optically-active two O-methoxy benzoyl tartrate.
At this, as amine and the tartaric diastereoisomeric salt of diacyl, any combination is all no problem, for example:
The situation of (1) optically-active dibenzoyl tartaric acid, preferred 1,3-amino-pyrrolidine, 1, the salt of 2-diamino-cyclohexane, Alpha-Naphthyl ethylamine, α-phenyl amine, 1-methyl-3-phenyl propyl amine etc.
(2) the tartaric situation of optically-active two toluoyl bases; the salt of preferred 1, α-(rubigan) ethylamine, α-(toluyl ethyl) amine, 1-methyl-3-phenyl propyl amine, 2-cyclopropyl Trans-4-Amino Cyclohexanol, 3-phenyl-1-propyl group piperidines etc.
(3) the tartaric situation of optically-active di-p-methoxy benzoyl, the salt of preferred 1, the amino valeronitrile of 3-, 1-methyl-3-phenyl propyl amine etc.
At this, optically-active diacyl tartrate is meant and comprises D body and L body, optical purity be 98%ee or more than.
Acidic aqueous solution is not particularly limited inorganic aqueous acids such as preferred hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid, more preferably hydrochloric acid, sulfuric acid, phosphate aqueous solution, especially preferably hydrochloric acid, aqueous sulfuric acid.Acid concentration is 2～40 weight %, preferred 5～30 weight %, more preferably 7～20 weight %.The acid consumption so long as in diastereoisomeric salt the equivalent of contained amine or get final product preferred 1.5～3.0 equivalents, more preferably 1.8～2.5 equivalents more than the equivalent.Therefore the normally bulky compound of optically-active diacyl tartrate preferably determines acid concentration and consumption, so that the concentration that the tartaric slurry of optically-active diacyl of separating out by the salt exchange can stir efficiently is 5～15%.
When the tartaric salt of optically-active directly being added in the acidic aqueous solution of stirring, separate out optically-active diacyl tartrate immediately and form the shape of determining, because the tartaric salt of optically-active also is blended in the block, the salt exchange can not be carried out smoothly.Particularly as the industrial method for preparing optically active amine, when splitting with the optically-active tartaric acid derivatives, the rate of recovery of optically active amine also reduces, so not preferred.In addition; if in alkaline aqueous solutions such as sodium hydroxide, add diastereoisomeric salt; owing to forming disodium salt, optically-active diacyl tartrate is dissolved in the aqueous solution; the salt exchange can be carried out smoothly; if but be diluted to the concentration of not separating out diacyl disodium tartrate salt; the optically active amine time-like that extracts unbound state must use a large amount of organic solvents, maybe must use the high halogen series solvents such as chloroform of extractability, is not preferred as the industrially preparing process of considering environmental pollution.In addition; optically-active diacyl tartrate can be by basic hydrolysis; the tartaric rate of recovery of optically-active diacyl is reduced; and the optically-active diacyl disodium tartrate salt in the adjusting aqueous solution is to acid; partial crystallization filters the tartaric chemical purity of optically-active diacyl obtain also to be reduced etc., is not preferred utilizing again.
Carry out smoothly for salt in aqueous acid is decomposed, in aqueous acid, add in advance with the salt of amine or with the diastereoisomeric salt of optically active amine in the similar optically-active diacyl tartrate of material that contains.Addition is different because of the tartaric kind of optically-active diacyl, salt give-and-take conditions, 0.05～3 weight % of the preferred acid aqueous solution, preferred especially 0.1～2 weight %.When the speed of interpolation amine salt or diastereoisomeric salt was fast, the optically-active tartrate consumption of Tian Jiaing was many in advance, when interpolation speed is slow, even addition also can carry out the salt exchange less well.Even the exchange of the many salt of addition is also no problem, but the tartaric utilization again of optically-active diacyl that reclaims increases, and can not become effective preparation method, so not preferred.
Preferred 0～50 ℃ of the temperature of salt exchange, more preferably 20～40 ℃.As long as just can carry out the salt exchange well in this scope, if be higher than 50 ℃, the salt exchange velocity accelerates, but owing to the different molten states that become of the tartaric kind of the optically-active diacyl of separating out, so the caking easily that therefore becomes is not preferred.
The salt clearing house takes time because of the kind of the temperature of salt exchange and salt is different, is generally 1～10 hour.In the optically-active diacyl tartrate slurry that adds in advance, amine salt or diastereoisomeric salt have been added; therefore be difficult to hold the situation of salt exchange; but amine salt or the diastereoisomeric salt situation different with the tartaric crystal formation of optically-active is many, as long as therefore examine the situation that salt exchanges of just holding.For the correct salt exchange situation of holding, can adopt the method for measuring dissolved amine amount in the aqueous acid.In addition, when the mother liquor that uses the salt of solid-liquid separation purpose optically active form in the optical resolution operation to obtain carries out the salt exchange, remove organic solvent the salt exchange is carried out smoothly through concentrating to wait in advance.If particularly do not remove the tartaric organic solvent of dissolving optically-active diacyl, the tartaric rate of recovery of optically-active diacyl can reduce, so not preferred.When filtrated stock is the mixing solutions of water and water-miscible organic solvent, can use decompression in advance to remove the aqueous solution of organic solvent.When filtrated stock is the aqueous solution, can directly use, but salt decomposes concentration in the operation when becoming excessive rarefied when directly using, and after concentrating adjustment concentration, can adopt the salt switching method of above-mentioned diastereoisomeric salt.In addition, during in the optical resolution operation and with organic carboxyl acids such as optically-active diacyl tartrate and mineral acid or acetate, contain these acids in the filtrated stock, but, decompose in the operation and can directly use at salt so long as water miscible acid is same as described above.When being not water soluble acid,, when using the optical resolution operation again, carrying out the salt adjustment and get final product though be blended in the optically-active diacyl tartrate of separating out.
Like this, with containing that the tartaric aqueous acid of optically-active diacyl carries out salt exchange and the optically-active diacyl tartrate slurry proterties that reclaims is also good.Can adopt filtration under diminished pressure, pressure filtration or centrifugal dewatering method during optically-active diacyl tartrate that recovery is separated out, it is also good that the optically-active diacyl tartrate that is reclaimed by present method filters proterties.The optically-active diacyl tartrate optical purity that is reclaimed by present method does not reduce, and chemical purity is also high.
When the optically-active diacyl tartrate that reclaims is used as the starting raw material of optical resolution, also can utilize again after the drying, resolution solvent so long as water or water-containing solvent just can directly utilize again.
There is no particular limitation to the method for optical resolution, for example can in solvent racemic amines be mixed with optically-active diacyl tartrate, behind the synthetic diastereoisomeric salt, carries out optical resolution by separating out this diastereoisomeric salt.
